Caching Issue

I think in general, NoteForms' cache could be improved. Some issues:

- Updated to Pro account but in the logged in page, it still says "You are currently on the free plan. Upgrade to use all features."

- After editing database views or forms, when accessed through the same browser, most of the time the changes could only be seen after several refresh or if the link is accessed through incognito window or different browser.

- Chat history with Customer Support logged in from account A will still be shown even after logging from account B - through the same browser.
